H&M is now teaming up with Burberry, but not doing clothes.
A fashion industry charter for climate action was formally launched at 2018's United Nations climate change conference, COP24, in Katowice, Poland.
Support for the new charter has come from high street retailers, luxury fashion houses and other suppliers within the sector. Stella McCartney, Burberry, Adidas and H&M Group are included in the list of 40 signatories.
Aligned with the goals of the Paris Agreement, the new charter includes 16 principles and targets.
The companies involved have committed to reducing their aggregate greenhouse gas emissions by 30% by 2030 and they've agreed to prioritize low-carbon transportation suppliers and favor climate-friendly materials.
Stella McCartney, whose eponymous label is already a leading player in sustainable fashion, was one of the founding signatories.
She announced her involvement in late November during Voices, a fashion industry conference staged in the English countryside, where she was also honored for her work in the sector.
During an interview at the conference, she acknowledged the complexities of working sustainably and responsibly: "There are millions of limitations from a design and creative point of view. There are millions of limitations from a sourcing and manufacturing point of view. But for me, all of those challenges are part of being a designer and part of being a businesswoman."
The multitrillion-dollar business of fashion, with its complex and long supply chain, is worryingly vexed with problems contributing to climate change.
The fashion industry emits more greenhouse gas than all international flights and maritime shipping journeys combined, and it's estimated that a garbage truck's worth of clothing is either burned or sent to a landfill every second.
On top of that, thanks to our powerful washing machines, our clothes pollute the ocean with microfibers equating to approximately 50 million plastic bottles each year.
